Data from "Locomotive Engines at the Paris Exhibition", The Artizan, Vol II, 4th Series, #2 (11 February 1868), p. 27.
Data from W H Maw and William Dredge, "Locomotives", Reports on the Vienna Universal Exhibition, Part II (London: George Eyre and William Spottiswoode, 1874), p. 399.
Maw and Dredge describe this little saddle tank as "...requiring no special notice".
